The Single In-Line System is a convenient under sink system that has both advantages and dis-advantage.
It has the advantage of not requiring an additional hole in the sink for a separate tap, however, the main disadvantage is that there is only one Cartridge, so it is not as effective as the Ultra Premium.
So it is a matter of weighing up the advantages and disadvantage and making that informed decision. If you need more help with that choice call the friendly staff at the shop for further advice.
